of this character, having wings which are readily adjustable so as to occupy different extended as well as normal positions.

It is especially aimed to provide such a construction wherein connection at all times and at all adjustments between the wings and the remainder of the sweep is rigid, and consists of inter-engaging ribs and slots and bolts or the like.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embo-diment.

In said drawing:-

Figure l is a plan View of the sweep;

Figure 2 is a bottom or inverted plan view of the sweep;

Figure 3 is a longitudinal sectional view taken on the line 33 of Figure 1;

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 1; and

Figure 5 is a cross sectional view taken on the line 55 of Figure 1.

Referring specifically to the drawing, l designates a plow sweep or the like generally of conventional configuration, being pointed, as shown, and curved longitudinally and transversely, as desired. Such sweep is made in a single piece and has integral wings II at each side thereof, extending rearwardly. A central stub I2 on said sweep has a central longitudinally extending slot I3 to accommodate means to fasten the same to a beam or the like. The rear end edges of the wings I I are preferably beveled or chamfered, as shown, at M.

Disposed against the under surfaces of the wings II are extensions or adjustable wings l5, whose rear or free ends conform generally in shape to the free or rear ends of the fixed wings II. Such adjustable wings l have central 1ongitudinal slots l6 therethrough, which snugly and slidably engage depending longitudinal ribs l'l integral with the fixed wings H. As a result of this construction, the extensions or adjustable wings l5 are slidable relatively to the wings H, and may be arranged at any desired adjustment or extended position with respect to the wings I I. Removable bolts rigidly secure the wings IE to the wings H and comprise a shank 18 extending through openings IS in the wings I l and through the slots l6. Such shanks l8 have countersunk heads 20 engaging enlargements of the openings I9, and also have nuts 2! threaded thereon and abutting the under surface of the wings l5.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:-

1. A sweep of the class described, having wings, extension wings engaging the under surface of the first-mentioned wings, means to secure the last-mentioned wings in adjusted position with respect to the first-mentioned wings, comprising ribs on one set of wings, the other set of wings having openings in which said ribs are disposed, and fastenings passing through the wings of the different sets.

2. A sweep of the class described, having wings, extension wings engaging the under surface of the first-mentioned wings, means to secure the last-mentioned wings in adjusted position with respect to the first-mentioned wings, the first- C. RESSER SMITH.
